To @ZZ zoll/Q71?) rit may concern,.-

Y Be it known that we, HARRY STTLLsoN HART and OTTO W. MEISSNER, citizens of the United States, residing at Chicago,A in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dump- Cars, of which the following is a specification. The invention relates principally to that class of dump-cars which isjprovided with IO dumping-hopperbottom portions, commonly called Rodger dumping-cars, which dump ballast between the tracks in a typical manner, and particularly to the means by which a maximum opening may be provided for the discharge of material other than ballast, such as coal and the like. n

The invention has further reference to the means for opening and closing the discharg-4 ing mechanisms and holding them in operative closed position, all of which will more fully hereinafter appear.

The principal object of the invention is to provide a simple, economical, and efficient .hopper-bottom dumping-car with discharging 2 5 mechanism by which a maximum opening may be provided.

vA Ifurther object ofthe invention is-to'provide a hopper-bottom dumping-car with means by which the discharging mechanism may be heldin closed operative position, all of which will more fully hereinafter appear.

The invention consists principally in a hopper-bottom dumping-car in which there are combined a supporting-frame portion, a V- shaped hopper portion extending longitudinally of the car with its apex arranged below the 4underframing and at or near the vlongitudinal center thereof, the inclined side lpor- 4-O tions of which are provided with lower swinging portions forming a part thereof, and means for closing such swinging portions successively, iirst one and then the other, by and during oneand the same operation, substantially as hereinafter setforth.

Theinvention consists, further, in a hopperlbottom dumping-car in which there are combined a supporting-framework, a V-shaped ,scribed that which we consider to be new,

hopper portion extending longitudinally of the car with its apex arranged below theunderframing and at or near the longitudinal center thereof and having inclined side por- `tions which form the hopper proper and are struction hereinafter described and claimed.

In the'accompanying drawings, Figure 1 is a cross-sectional elevation ofa portion of a car as it appears when constructed in accordance with these improvements; Fig. 2, an enlarged plan view of a portion of one of the lower swinging sections of the hopper looking 7o at the same from below; Fig. 3, an enlarged perspective detail of the bolt and staple mech- `anism for locking and holding the swinging seetlons 1n closed position; and Flg. 4L, anenlarged perspective view of one portion of the lighter swinging section, showing the staple e vmechanism attached thereto. -30 closed by and-during the same operation and VIn illustrating and describing these improvements we havey only illustrated and de- 8 O taken in conncction with so much that is oldA as will properly disclose the invention and enable those skilled in the art to practice the same, leaving out of consideration other and well-known elements, which if shown and described herein would only tend to confusion, prolixity, and ambiguitymf ,y

In constructing a carrin accordancewith these improvements we provide a supportingframework vhaving side sills a and intermediateysills 7) extending, as is usual,, longitudinally of the car and tied together byfany wellknown means, and which is furtherprovided with-needle or deck beams c. To provide for carrying the load in the car we make a V- shaped hopper portion and so arrange it that it extends longitudinally of the car, with its apex arranged below the intermediate sills and at or near the longitudinal center thereof. This hopper portion proper is Jformed or constructed so that it has two inclined side portions extending from a point at or near the upper outer sides of the car and inclined downwardly and inwardly until they meet at the apex, as above suggested, below theintermediate sills and at or near the longitudinal center of the car. Each of these inclined side portions is divided into two sections, an upper lixed section s, having its lower edges attached to the intermediate sills and arranged above the same, and lower swinging sections c and f pivotally attached to the intermediate sills and below the same, so that they may both be opened and closed to provide for the discharge of material through a maximum opening, being the opening or space r/ directly between the intermediate sills, which opening permits of all kinds of material being discharged without any clogging or sticking. To provide for the opening and closing of these swinging sections, one of such sections, preferably e, which is farthest removed from the closing mechanism, is made heavier than the sectionf, or, differently stated, the swinging section f, which is nearest to the closing mechanism, is made lighter than the farther swinging section e, so that by the closing mechanism hereinafter described the lighter swinging section f is first brought into position until it contacts the cleat or stop 7i, when the heavier section is operated and swung into position until it also contacts a cleat or stop 1l, and both of such sections are positioned. To hold such parts in their closed and operative position, the lighterswinging section is provided with a plurality of stapleplates j', having perforations if: therein, while the heavier swinging section is provided with a multiplicity of locking-bolts Z, inclined at their lower ends and arranged to enterl the perforations in the staple-plates. This heavier swinging section is also provided with a rockshaft m, having an operating-handle a thereon and connected with the locking-bolts by means of links p, so that as such rock-shaft is rocked or vibrated the locking-bolts are either moved into engagement with the staples or extracted therefrom to permit of the desired operations. A locking-link q is provided and pivotally attached to the upper part of the heavier swinging section, so that it may engage the free upper end of the operating-handle and hold the parts in locked position.

To move the doors into their operative p0- sition by and during one and the same operation, the lighterswinging section first and the heavier last, a second rock-shaftfris provided and movably mounted in the supportingframework of the car. Secured to this rockshaft are one or lmore chains t, which chains are also secured to the lower end oi the heavier swinging section. ,lhe lighter swinging section is provided with a .bracket u lor each chain at or near its lower free end, and sueh bracket is further provided with an idler-pulley e, directly contacting' such chain, so as to minimize the frictional engagement therewith, all of the parts being arranged, as will be seen from an examination of the drawings, so that as the chain is tightened the lighter section is first brought into position and then the heavier swinging section to enable it to be locked with the lighter section.

We claim*- l. In a hopper-bottom dumping-ear ol the class described, the combination of a supporting-frame portion, a V-shaped portion extending longitudinally of the car with its apex arranged below the underlriinning and at or near the longitudinal center thereof, the inclined side portions of which are provided with lower swinging sections forming a part ol each ol the inclined sides of the car, and means for closing such swinging sections successively iirst one and then thc other--by and during one and the same operation, substantially as described.

2. In a hopper-bottom dumping-car oi the class described, the combination oi a supporting-framework, a V-shaped hopper portion extending longitudinally of the car with its apex arranged below the underpinning and at or near the longitudinal center thereof and having inclined side portions which form the hopper proper and are divided into two sectionsupper iixed sections secured` to the frame of the car above the ul'iderpinning and lower swinging sections secured to and extending below such underpinning of the car and one of such swinging sections being heavier than the other, whereby the lighter swinging section is closed lirst and acts to limit and hold the second in position, substantially as described.

3. ln a hopper-bottom dumping-car ol the class described, the combination of a supporting-framework, a V-shaped hopper portion extending longitiulinally of the car with its apex arranged below the underpinning and at or near the longitudinal center thereoil and having inclined side portions divided into two sections-upper fixed sections secured to the framework of thc car above the underpinning and lower swinging sections pivotall y secured to the framework of the car below the underpinning, one of such swinging' sections being lighter than the other, whereby it is closed first and acts to limit the movements ol the second, a single rock-shaft, chain mechanism secured thereto and to the heavier lower swin ing section and contacting the lighter so that the lighter swinging section is lirst closed and acts to limit or hold the second and heavier swinging section in position, substamiially as described.
